comment Best sensor for balancing inverted pendulum
Check out the dIMU sensor which provides both accelerometer and gyroscope for all three axises in one sensor. It doesn't have a nice casing though.

comment Interfacing Mindstorms NXT 2.0 with webcam
What do you want to do? The NXT processing power and memory is limited after all. Do you want to have the webcam connected directly to the NXT, or will it be connected to a computer? If you go with the latter it is highly language specific, as you need libraries to interact with the NXT and the webcam. If you need the first I think NXTCam is the only option currently.

comment Is it possible to display large text on an NXT using LabVIEW?
I'm the author of RICcreator, a slightly more modern alternative to nxtRICEdit, so I should be able to answer about anything about the RIC format if you need help. (constantly hitting enter ruined this comment... -__-)

comment Is it possible to display large text on an NXT using LabVIEW?
RIC files can take parameters and display accordingly. RIC fonts are based on this idea, they take the character to draw as the first parameter, which then causes them to display the proper character. The extended NXT firmware has a special function which uses such a file to automatically display all characters. You can do it yourself pretty easily if all characters are the same width though.

comment How to simulate Lego Mindstorms programs written in C#?
I think you might be able to do something like this with Microsoft Robotics Studio. Here is a video that appears to do what you want: youtube.com/watch?v=AcETVcobqfc

comment Can an axle be removed from this 'brick paradox'?
Remember that (at least the newer) axle joiners have holes in the middle, so once you have one out you can use a long tin object to push the other out. I'm wondering if you could use the notch in the 2m axles to do this without damaging it? I do not remember how I got it out myself when I experienced this paradox myself though. (I was like: hmm, if you do this you shouldn't be able to get it out... Oh snap...)

comment What are all the different accessories that I can get for an NXT?
The older RCX sensors and motors works just fine with NXT and the PF motors can also be used together with the NXT, either by cable (PF->RCX + RCX->NXT) or by using a IR sensor. Should we add those as well?

comment How to repair leaky pneumatics?
Until recently no sets containing pneumatics had been produced for years, so they had become rather rare while still having demand. I thought it would have improved by now, but I guess stock is still low...

comment How to repair leaky pneumatics?
I have tried disassembling one and there are three rings. In the bottom of the piston is a fairly wide ring made of rubber. Then comes a small spacer of ordinary plastic. At the top there is a fairly complex part made of rubber and sadly this is the one which is normally causing trouble. Getting a replacement for this one will be difficult... I will add a photo in the question.

Great idea, thanks.

comment How can I make a working pin tumbler lock?
I like the solution, as I made something similar, but not near as compact as this in the past. (I used rubber bands to provide the spring effect though.) However what I didn't solve however was how to make it rotate nicely while still keeping the pins in the right position, so they wouldn't fall down when you rotate it. Any ideas to this?

comment How can I use more than three motors with one NXT brick?
I added 4 examples. I had to recreate 2 of them, since the original photos were either too blurry, or that the actual mechanism was hidden away inside the construction.

comment How can I use more than three motors with one NXT brick?
Yes, it can be done as a physical solution. I will try to dig up some old photos (and perhaps take some new ones), however it will have to wait for tomorrow.
